atto/unav? THOMAS ZJIMMEAN, OlE CLEVELAND, OI-HO, ASSIGNOR TO THE STANDARD PARTS COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OI-HO.

To all whom t may concern: y

Be it known that ll, 'llnoMAs ZIMMERMAn, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga,

Referring to the drawing, 10' indicates the axle housing which is provided vwith an endv flange 11 to which the extension 12 is secured, this extension having the flange 13 which is secured to flange 11 by rivets 14, or in any other suitablemanner. rllhe driving shaft is indicated at 15 and has the lintegral collar 16 formed thereon, Within the extension 12. The Wheel 17 is secured to the outer end of theshaft 15 by means of the taper fit 18 and the nut 19, a key 2O being also provided. The particular method of securing the wheel to the shaft 15, however, forms no part 'of the present inven-v tion.

The extension 12 is provided 4with a bore 21 preferably slightly larger than the bore of the housing 10 and in this bore the roller bearings 22 and 23 are supported.

rllhe end of the housing 10'constitutes an abutment for the bearing 23, and both bearings abutting the collar 16 and being oppo- .sitely arranged as shown so that, together, these will be capable of taking thrusts in both directions. 'llhe bearings 22 and 23 are of the conical roller t pe and in order to secure them and the slilaft 15 against axial movements a ring nut 24 is threaded in the outer end of the extension 12 and engages the bearing22 as shown. The ring 24 is ad-l justable, as.- will be readily noted, and is locked by means of the dog 25, the latter being held by the bolt 26. The ring 24 may have a soft packing 27 coperating witha l Smooth outer. surface 28 on the hub of the Specication of Letters Patent.

wheel 17, for the purpose of preventing the lubricant ,for the bearings 22 and 23 from escaping. rllhe bearings 22 and 23, being held against axial movements relative to the housing 10 and a shaft 15 being held, by the collar 16, against axial movements relative -to the bearings, it will be evident that the arrangement which l have provided constitutes a simple and eiiicient means for taking end thrusts in the shaft 15 and avoids ditliculties which arise from the prior con- Y structions wherein there is a single bearing ings, and adjustable means at the end of saidhouslng for securing said bearings and shaft.

2. In an axle, the combination of a housing, a driving shaft therein, a collar on said shaft, awheel lmounted on the outer end of said shaft, a pair of roller bearings on opposite sides of said collar supporting said shaft in said housing and adapted to take end thrust in either direction, an abutment on the interior of said housing engaged by` the innermost of said bearings, and an adjustable ring at the outer end of said housing coperating with said abutment to holdsaid bearing from movement in either direction in said housing. f

3. In an axle, the combination of a hous- ,ing having a flange at the end thereof, an.

extension for the vhousing secured to said langeand bored to receive bearings, a shaft in said-housing having a collar Within said extension, a pair of roller bearings engaging opposite sides-.of said' collar the innermost of said bearings abutting .the end of said housing, and a ring adjustably arranged in the outer end of said extension and engaging the outermost of said bearings to hold the same against axial movement.

ln testimony whereof ll aix my signature.
